Ko te tautenga inductive ki te ara iahiko AC

Ātete i roto i te ara iahiko hiko ko o rua momo - kaha, me te urupare. parenga Hohe māngai, aano atu, coils whakawera, me te pera i runga i. I roto i te mau parau te tahi atu, te āhuatanga katoa i roto i nei tika mahi te rere o nāianei mahi whai hua ranei, i roto i te take motuhake, ki te whakaputa i te kaiwhakahaere whakawera e hiahiatia ana. I roto i tahuri, i te jet - he wā matua. E pā ana te reira ki te tautenga kahapupuri inductive. Te āhuatanga iahiko he tautenga, te wahi o te nāianei hiko puta ngā faafariuraa pūngao takawaenga. He pūnga (te puritanga) piki te tiaki, me ka tukua te reira ki te koropiko. Ko tētahi atu tauira - te tautenga inductive o te pōkai, e tahuri ai te wahi o te pūngao hiko ki te papa autō.

I roto i te meka, "parakore" kore reactances hohe ranei. Ngā wā katoa ko reira te wāhanga ritenga. Hei tauira, ka tātai i te waea mō ngā rārangi mana roa-tawhiti, tango ki pūkete e kore anake te ātete, engari capacitive ano hoki. A, whakaaro te tautenga inductive, me e maharatia ana e ia e hanga e rua nga whakahiko me te supply te mana tahi mau huringa i roto i te tātai.

Na roto i te whakatau i te katoa parenga o te wahi mania, he mea e tika ana ki te korukoru te wāhanga hohe, me te urupare. Ano, ki te tiki i te moni tika o te whakahaeretanga o pāngarau mua taea, na whakamahi āhuahanga (pere) ara ki te hanga. Hanga he tapatoru tika he parenga ia kaha, me te inductive nei cathetus rua, me te tāroa - tonu. Ko te roa o te wāhanga e ōrite ana ki te uara o nāianei.

A feruri tautenga inductive ki te ara iahiko AC. Tohu i te taiawhio ohie arā, o te puna mana (emf, E), he parenga (wāhanga parenga, R) me te pōkai (hiko, L). Mai te mea e tika ana te tautenga inductive ki whaiaro-piri EMF (E B) i roto i te hohoko o te pōkai, he reira kitea e faarahi te reira i ki te hiko haaati me uara hua o te nāianei e rerengia ana i roto i te ara iahiko.

rite te ture a Ohm mo tenei ara iahiko titiro:

E + E B = ahau R.

I muri te whakatau i te pärönaki wa o te nāianei (PR ahau) ki te tātai i te whaiaro arataki-:

E si = -L * Ave ahau.

"-" tohu i roto i te whārite tohu e whakahaua te pānga o E si ki te huri i te uara o nāianei. kī Lenz ture e te mea i reira ko tetahi huringa ki te EMF whaiaro-piri nāianei. Mai taua huringa i roto i te ara iahiko AC e tūturu (me he tonu), hanga te E B he ātete nui e ātete pono hoki ranei. I roto i te take o te puna te mana o nāianei tika , e kore te mea makona tenei whanaungatanga me ka ki te whakamātau hono te pōkai (hiko) i roto i te ara iahiko taua pai puta matarohia poto-iahiko

Ki te hinga i te E supply mana B me te whakaputa i te rerekētanga pea i roto i te kitenga pōkai i ko reira nui, i te iti rawa i runga i E si resistance utu. whai te reira:

U = si ngeru -e.

I roto i te mau parau te tahi atu, te ngaohiko puta noa i te pūpoapoa ko numera rite ki te Ākinga Pūngao o te whaiaro arataki-.

Mai ki te whakanui ake i nāianei i roto i te ara iahiko whakanuia ana te papa autō i tahuri mahia mara Eddy meinga tupu i roto i te hiko countercurrent, ka taea e tetahi atu ki taua reira ko he neke wā i waenganui i te ngaohiko me te nāianei. No reira kotahi āhuatanga: no te mea ārai te whaiaro arataki-EMF tetahi huringa i roto i te nāianei, ina whakanuia ana te reira (te wā hauwhā tuatahi o te sinusoid i) counter mara e hangaia, ko te hinga (wā tuarua) i runga i te anga ke - te piri o nāianei ko codirectional ki te turanga. Ko, ki te te postulate te oraraa o te puna mana pai, kahore parenga ā, me te hiko i waho te wāhanga hohe, te wiri pūngao "pūtake - pōkai" taea puta ta'engata.
